Answer:
20 students offered both physics and biology.
Step-by-step explanation:
n(Total) = 50
n(Physics) = 40
n(Biology) = 30
Let n(Physics and Biology) = x
n(Physics only) = 40 -x
n(Biology only) = 30 - x
40 - x + 30 - x + x = 50
70 - x = 50
x = 20

solve the enquality 2x+1>11
Step-by-step explanation:
2x+1>11 1 is positive integers so it have to be cancelled by negative integer 1
2x>11-1
2x>10 two will be cancelled by two to get x
then we divide 2 from 10
x>5 this means x is greater than 5
{x=6,7,8,...}

Answer:
(a) (2x +36)° +(3x +14)° = 90°
(b) ∠C = 38°; ∠D = 52°; ∠E = 90°
Step-by-step explanation:
(a) Two acute angles are marked in a right triangle. We know the sum of angles in a triangle is 180°, so if one of those angles is 90°, the sum of the other two angles must be 90°. We can use that fact to write and equation for x.
(2x +36)° +(3x +14)° = 90°
__
(b) We can collect terms, subtract 50 and ...
5x +50 = 90 . . . . . . . collect terms, divide by °
5x = 40 . . . . . . . . . . subtract 50
x = 8 . . . . . . . . . .. divide by 5
∠C = (3x +14)° = (3·8 +14)° = 38°
∠D = (2x +36)° = (2·8 +36)° = 52°
∠E = 90°
_____
Angle E is marked as a right angle by the little square in that corner. The measure of a right angle is 90°, by definition.

The midline is y =
The amplitude is
The period is

The midline is y = -2, the amplitude is 1.5, and the period is 4π if the because function completes one revolution in 4π.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
From the graph:
The midline is the horizontal line about which the graph of a function oscillates
y = -2
The amplitude is the half vertical distance the function travels around the midline.
Amplitude = 1.5
The period: the distance traveled to complete the one rotation:
Period = 4π
Thus, the midline is y = -2, the amplitude is 1.5, and the period is 4π if the because function completes one revolution in 4π

!WORTH ALL MY POINTS!
ASAP
Answer:
Daniel spent $ 19.
Step-by-step explanation:
Given that, while shopping for clothes, Tracy spent $28 less than 2 times what Daniel spent, and Tracy spent $ 10, to determine how much Daniel spent the following equation must be performed:
Daniel: X
Tracy: 2X - 28 = 10
2X - 28 = 10
2X = 10 + 28
X = 38/2
X = 19
2x19 - 28 = X
38 - 28 = X
10 = X
So, Daniel spent $ 19.

Janessa is playing a board game with two friends. Using a single die, one friend rolled a four, and the other friend rolle
a three. Janessa needs to roll a number higher than both friends in order to win the game, and she wants to calculate
her probability of winning.
How many desired outcomes should Janessa use in her probability calculation?
A. 3
B. 6
C. 4
D. 2
Answer:
D. 2
Step-by-step explanation:
The only possible outcomes that Janessa could possibly calculate would be 5 and 6. This is because a single die has 6 possible outcomes. If Janessa's friends rolled a 3 and a 4, and Janessa needs to roll something higher, then the only higher possible outcomes would be a 5 or a 6. Meaning that Janessa can only use a total of 2 desired outcomes for her to actually win the game.
